Association between serum asprosin and diabetic peripheral neuropathy in patients with type 2 diabetes mellitus in the community.

Abstract

This study aimed to investigate the relationship between serum asprosin level and diabetic peripheral neuropathy (DPN) in community patients with type 2 diabetes mellitus (T2DM). A total of 498 patients with T2DM were recruited from Zhuoma Community Health Service Station and Chengbei West Street Community Health Service Center in Changzhi City of Shanxi Province between November 2019 and July 2021. Their height, weight, and body mass index (BMI), as well as fasting plasma glucose (FPG), glycosylated hemoglobin (HbA1c), triglyceride (TG), and serum asprosin levels, were analyzed. Patients were divided into the DPN group (n = 329) and the non-DPN group (n = 169) according to the presence or absence of DPN. The t-test, Mann-Whitney U test, and χ² test were used to compare the indicators between the two groups. Pearson or Spearman correlation analysis was used to evaluate the correlation between serum asprosin and other clinical data. Multivariate logistic regression analysis was used to analyze the influencing factors of DPN. Compared with the non-DPN group, the DPN group had higher serum asprosin (p < 0.05). The prevalence of DPN gradually increased according to the tertiles of asprosin (56%, 67%, and 75%; p < 0.05). Multivariate logistic regression analysis showed that after adjustment for covariates, patients with asprosin concentrations between 295.4-367.0 pg/ml and concentrations > 367.0 pg/ml had a higher risk of diabetic neuropathy compared than those with asprosin levels < 295.4 pg/ml (p < 0.05). Serum asprosin was found to be positively correlated with DPN, and it resulted as an influencing factor for DPN in patients with T2DM in the community. With the increase of asprosin, the risk of DPN also increased.
